Moreover, a groove is disposed on a side of the exterior cover opposite to the insertion part, and a side of the insertion part opposite to the exterior cover is inserted into the groove to tightly fit the groove.

Moreover, a USB hole is disposed on the USB port of the case, and the USB hole is provided with a protrusion having an annular shape, and a width of the protrusion on one side of the first extending part is greater than a width of the protrusion on the other side, and an end of the USB cover opposite to the protrusion abuts against the protrusion, so that a space is formed between the first gap, the second gap and the protrusion.

Moreover, a columnar connection rod extending along a direction toward the protrusion is disposed on a side of the insertion part opposite to the first extending part, and a socket is disposed on the protrusion at a position opposite to the columnar connection rod, and the columnar connection rod inserts into the socket.

Moreover, a position limiting block with a diameter greater than the socket is disposed on the columnar connection rod.

Moreover, the USB cover further comprises a connecting part for inserting into the groove provided between the insertion part and the exterior cover, and the connecting part extends towards the first extending part to secure with the columnar connection rod, and the insertion part is secured with the connecting portion.

Moreover, the USB cover is made of a soft material.

The present invention also provides an electronic product comprising the USB cover connecting structure of the electronic product.

Compared with the prior art, the present invention forms a gap between the extending parts and sidewalls of the USB cover by disposing an extending part on opposite sides of the USB cover, so that while one of extending part is pressed and the other one will be lifted, thereby forming a digging position for a finger to pull the USB cover out easily. Costs of the mold and the production cost are reduced due to removal of the groove.

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

As shown in FIG. 1 , FIG. 2 , and FIG. 3 , a universal serial bus (USB) cover connecting structure of an electronic product of the present invention comprises a USB port 1 and a USB cover 2 covering the USB port. A USB hole 11 is disposed on a case 10 of the electronic product at a place opposite to the USB port 1 . The USB cover 2 covers the USB hole 11 on the case 110 , and the size and the shape of the USB cover 2 match the size and a shape of the USB hole 11 . The USB cover is made of a soft material. The USB port 1 is fixed on a base 17 , and the base 17 is secured to the case 10 by screws.

As shown in FIG. 2 and FIG. 3 , the USB port 1 is formed with a flat shape, having a long edge and a short edge. A first extending part 3 and a second extending part 4 are disposed on two ends of the USB cover 2 opposite to the short edges of the USB port 1 , forming a first gap 5 and a second gap 6 between the first extending part 3 , the second extending part 4 , and sidewalls of the USB cover 2 .

A protrusion 12 having an annular shape is disposed on the USB hole 11 , and a width of the protrusion 12 on one side of the first extending part 3 is greater than a width of the protrusion 12 on the other side. An end of the USB cover 2 opposite to the protrusion 12 abuts against the protrusion 12 , so that a space is formed between the first gap 5 , the second gap 6 , and the protrusion 12 .

While opening the USB cover 2 , the first extending part 3 is pressed by a finger to lift the second extending part 4 up, so that a space allowing insertion of a fingernail is formed between the second extending part 4 and the USB hole 11 , therefore the second extending part 4 is dug out and the USB cover 2 can be entirely removed. Therefore, the USB cover can be designed without considering the position occupied by the groove, so that a more beautiful and complete appearance can be applied.

As shown in FIGS. 2 and 3 , the USB cover 2 may comprise an insertion part 7 for inserting into the USB port 1 and an exterior cover 8 exposed above the case, and the first extending part 3 and the second extending part 4 are disposed on the exterior cover 8 . A groove 9 (shown in FIG. 4 ) is disposed on a side of the exterior cover 8 opposite to the insertion part 7 , and a side of the insertion part 7 opposite to the exterior cover 8 is inserted into the groove 9 to tightly fit the groove 9 , thereby forming a whole component. A columnar connection rod 13 extending along a direction towards the protrusion 12 is disposed on a side of the insertion part 7 opposite to the first extending part, and a socket 14 is disposed on the protrusion 12 at a position opposite to the columnar connection rod 13 inserting into the socket 14 . A position limiting block 15 with a diameter greater than the socket 14 is disposed on the columnar connection rod 13 , thereby preventing lost and entire removal of the USB cover 2 from the case 10 after being pull out.

As shown in FIG. 5 , the USB cover 2 further comprises a connecting part 16 for inserting into the groove 9 provided between the insertion part 7 and the exterior cover 8 . The connecting part 16 extends towards the first extending part 3 to secure with the columnar connection rod 13 , and the insertion part 7 is secured with the connecting part 16 tightly connecting the groove 9 .

As shown in FIG. 3 , a first hole 18 allowing penetration of the columnar connection rod 13 is disposed at a position of the base 17 opposite to the columnar connection rod 13 , and a second hole 19 connected with the first hole 18 is disposed on the base 17 . An aperture of the second hole 19 is smaller than an aperture of the first hole 18 , and the columnar connection rod 13 is a tapered shape. An end of the largest diameter is connected and fixed to the connecting part 16 , and an end of the smallest diameter of columnar connection rod 13 is inserted into the through hole 18 . Thereafter, because the diameter becomes smaller, an exterior wall of the columnar connection rod 13 and the through hole 18 are tightly connected, thereby preventing the USB cover 2 from falling out of the USB hole 11 .

The present invention also provides an electronic product comprising the above USB cover connecting structure of the electronic product.

The electronic product of the present invention can be a smart device such as a mobile phone, a smart watch or a smart bracelet.

While the invention has been shown and described with respect to the specific embodiments the embodiments of the embodiments of the invention various changes in details.
